rbokeh: overlay points on a boxplot

Hi,

Is it possible to do this in rbokeh (overlay observations on a boxplot)

http://www.zijdeman.nl/files/r_examples/boxplot_example.html

data(iris)

figure() %>% ly_boxplot(x=as.character(iris$Species), y=iris$Sepal.Width) %>%

	ly_points(x=as.character(iris$Species), y=iris$Sepal.Width)

is easy, but then when I tried to think of a way to jitter the points I ran into conceptual problems. ly_boxplots forces a categorical x-axis and jittering is a numeric x-axis.

Any ideas?

Thanks,

Jeremiah

Here’s an example:

dd <- lattice::make.groups(

a = rnorm(100),

b = rnorm(100, mean = 2),

c = rnorm(100, mean = 5)

)

dd$jitwhich <- paste0(dd$which, “:”, runif(min = 0.2, max = 0.8, nrow(dd)))

figure() %>%

ly_boxplot(data, which, data = dd) %>%

ly_points(jitwhich, data, data = dd, color = “black”)

In Bokeh, you can offset categorical values by appending a “:” followed by a number between 0 and 1. 0.5 is center. It would be nice to have a “catjitter" function - if you file an issue, this should be an easy addition.
